Description
Technical Field
The utility model relates to a split type brake drum has especially related to a split type brake drum.
Background
Generally speaking, in the design of a general brake drum, the design of a brake drum material is single and is not very important, generally HT250 or HT225, the main processes of the two materials are casting, so that the cost is always high, the product performance is not reduced while the cost can be effectively reduced under the large prospect of high-speed development of automobiles, and the brake drum becomes a key legal standard whether automobile part manufacturers can stand out or not.
Therefore, it is very necessary to design a new brake drum to replace the original brake drum.
SUMMERY OF THE UTILITY MODEL
In order to solve prior art brake drum material cost problem about high, the utility model aims at providing a split type brake drum, make the brake drum fall into two parts, the gray iron of pouring is used to the drum circle, and the drum lid is the steel of plate material, and panel passes through stamping forming one-tenth lid column structure to reduce material cost, stamping cost is less than casting cost far away, and the drum circle still uses gray iron metal material to guarantee the correlation ability simultaneously.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the brake drum is of a split structure and mainly comprises a drum cover and a drum ring, wherein the drum ring is in a cylindrical ring shape, the drum cover is in a circular mushroom shape, the bottom of the drum cover is horizontally folded towards the outer side, and the drum cover and the drum ring are positioned through a positioning pin and are fixedly connected through a bolt and a gasket.
The peripheral edges of the drum cover and the drum ring are provided with a plurality of pin holes, and a plurality of positioning pins firstly pass through the pin holes on the drum cover and are inserted into the pin holes of the drum ring.
The positioning pin is in interference fit with the drum cover and the pin hole of the drum ring.
The peripheral edge of the drum cover is provided with a plurality of unthreaded holes, and a plurality of bolts penetrate through the unthreaded holes and are connected into the threaded holes of the drum rim in a threaded mode.
The drum ring material is composed of gray iron.
The drum cover material is composed of a metal steel plate.
The utility model has the advantages as follows:
the utility model discloses the realization is guaranteed the performance requirement of brake drum, reduces product cost simultaneously, and to the commonality that the combination can improve the product for selection of two kinds of appearance spares of different specifications, save design and development cost.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 4, the brake drum is a split structure, and mainly comprises a drum cover 1 and a drum ring 2, wherein the drum ring 2 is in a cylindrical ring shape, the drum cover 1 is in a round mushroom shape, the bottom of the drum cover is folded outwards, the drum cover 1 and the drum ring 2 are positioned by a positioning pin 5, and the drum cover 1 and the drum ring 2 are fastened and connected by a bolt 3 and a gasket 4.
As shown in fig. 1 and 3, the peripheral edges of the drum cover 1 and the drum rim 2 are provided with a plurality of pin holes, and a plurality of positioning pins 5 are inserted into the pin holes of the drum rim 2 through the pin holes on the drum cover 1.
The drum cover 1 and the drum ring 2 are positioned through the positioning pin 5, and the positioning pin 5 is in interference fit with pin holes of the drum cover 1 and the drum ring 2.
As shown in fig. 1 and 2, the peripheral edge of the drum cover 1 is provided with a plurality of unthreaded holes, a plurality of bolts 3 are threaded into the threaded holes of the drum rim 2 after passing through the respective unthreaded holes, and a washer 4 is arranged between the female end of the bolt 3 and the hole end face of the unthreaded hole of the drum cover 1.
The drum ring 2 material comprises grey iron, and simultaneously drum ring 2 one side is equipped with a plurality of screw holes and a plurality of pinhole in drum ring 2 and the 1 laminating department of drum lid.
The drum cover 1 is made of metal steel plates, and a plurality of unthreaded holes and a plurality of pin holes are formed in the joint of the drum ring 2 and the drum cover 1 on one side of the drum cover 1.
Thus, the utility model discloses a structural design can greatly reduced the cost of brake drum, can guarantee the performance requirement of brake drum simultaneously again.
The above examples are for the description of the present invention, not for the limitation of the present invention, and any simple modification of the present invention all belongs to the protection scope of the present invention.
